I am going to be purchasing a new tv soon and am faced with a couple choices. I have always preferred plasma to LCD, but I prefer Passive 3D to active 3D, and I do plan on using 3D. My couch is also 14' from the wall where I will be mounting the tv, and I can't move it much closer, maybe a foot or two, but not more than that, so the size difference (47" on the LG vs. 55" on the Panasonic) is also a consideration. My room is moderately dark and I am planning on getting some blackout curtains for the windows that would be the biggest issues regardless of which TV I get. So what do you all think? 47" Passive 3D LCD vs. 55" Active 3D Plasma.
